Filed: 1929-05-14
Abstract: 329,502. Roberts, A. M., and Associated Electrical Industries, Ltd. May 14, 1929. Thermostats.-Heat is supplied to a container by means of a heating coil surrounding it, and the expansion of the container is employed to regulate the heating. The container 10, e.g., of steel in the austenitic condition, is heated by a coil 11 in circuit with the contacts 12 of a relay 13, the contacts being shunted by an adjustable resistance 14. The container is supported by knife edges 16 resting on supports 17 at one end, and by a pair of abutments 20 resting on a rocker 21 at the other end. The rocker rests on a pair of rods 22 of material having a low coefficient of expansion, such as that known by the registered Trade Mark " Invar," and the rods 22 are fixed at one end in the supports 17 and rest on rollers 23 at the other end. The rocker 21 carries an arm 25 with a pivoted and adjustable contact 26, and the lower contact 30 is pivoted to a bracket 31 attached to the ends of the rods 22. The member 30 carries a roller 32 bearing on a cam 33 actuated bv clockwork 34. When the temperature of the container 10 rises beyond a predetermined point, the contacts 26, 30 are closed, and the relay 37 is energized. The contacts 38 open, and the relay 39 is de-energized, thus removing the short-circuit from the resistance 14 and decreasing the current supply. The temperature at which the contacts 26, 30 are closed is varied throughout a cycle by the clockwork 34.

Patent GB-750273-A (GB)
Title: Improved driving coupling especially for looms
IPC: D03D51/00
Filed: 1954-05-24
Abstract: 750,273. Loom take-up mechanism. JUTE INDUSTRIES, Ltd., and PLENDERLEATH, J. S. May 24, 1954, No. 15163/54. Class 142 (2). [Also in Group XXIV] In a loom in which the take-up roller is driven continuously whilst the loom is running, commencement of take-up is delayed when the loom is restarted after weft breakage. A clutch member 15, Fig. 2, slidably keyed on the input shaft 1 is operated by a fork 20 loaded by a'spring 27 which tends to disengage the clutch; the driven clutch member 17 rotates the take-up roller through bevel gears 7, 8, reduction gearing 4, 10, 9a and a sprocket 9b. When the loom is started, a lever 31 rocks to bring a finger 30 carried by.it into engagement with a thread 12 on the input shaft 1, whereby the finger is traversed to push a plunger 36, housed in the fork 20, against the action of a spring 23; when the spring 23 is compressed sufficiently to overcome the load of the spring 27, the fork is moved to close the clutch. Whilst the loom is running, the finger 30 rides against the end force of the thread to keep the clutch engaged; when the loom is being stopped, the lever 31 rocks to withdraw the finger from the thread, whereupon the spring 27 opens the clutch. The delay between starting of the input shaft 1 and of the output sprocket 9b depends on the length of thread traversed by the finger 30 before it operates the clutch, and is adjusted by moving a shaft 29 endwise by means of a nut 39 to alter the initial position of the finger. In a modification, Fig. 3, the finger is replaced by a wheel 41 and the lever 31 passes along a fixed block 43 whilst the wheel is traversing the thread 12; when the wheel drops off the end of the thread, the lever 31 falls down the sloping end 43a of the block 43, thereby moving the wheel clear of the end of the thread 12.

Patent GB-312357-A (GB)
Title: Improvements in and relating to dynamo-electric machines more especially for electric arc welding
IPC: B23K9/10
Filed: 1929-05-16
Abstract: 312,357. Elin Akt.-Ges. f³r Elektrishe Industrie. May 25, 1928. [Convention date]. Dynamos, regulating; coils. - In a series excited dynamo feeding a load with an arc characteristic, for instance for arc welding with electrodes of different thicknesses several series coils are provided and these are connected in different ways for thin and thick electrodes so that they give a smaller effective number of ampereturns and a greater internal resistance for thin electrode work. The increase in resistance is not large enough to reduce the steady current appreciably but it reduces current surges. The following methods are described:-(1) A double armature generator with two series windings may have its two component machines, each comprising an armature and field coils, connected in parallel for heavy loads, one component machine being used for light loads, thus giving internal resistance values in the ratio 1 : 2. (ii) A single armature machine may have two series windings of different sections, or number of turns, the smaller one being used either alone or in series with the larger one for small load currents, and the thicker one either alone or in parallel with the thinner one for large currents. The field coils in this case are preferably strip-wound with the thin and thick-section coils sandwiched so that the thick ones when unloaded carry away heat from the thin ones; or the thin coil may surround the thick one to give it an increased length per turn. Fig. 4 shows a machine in which the arc 25 is connected in series either with the thin or thick series coils 21, 22 of a machine of the Rosenbeag type by throwing the switch on the contacts 29, 28 respectively, the thin coil having a smaller number of turns than the thick one. Alternatively, the two coils may have the same number of turns but a portion of the thin coil may oppose the remainder of its turns, thus giving a smaller effective number. Fig. 6 shows an arrangement in which the thick coils 22 are always in circuit. For a reduced load current and increased internal resistance, the thin coils 36, which have fewer turns, are connected in series with the coils 22 by removing the short-circuit at 37. In the form shown in Fig. 7, the machine has two field coils 41, 42 with different numbers of turns which are connected in parallel for heavy loads, as shown in full lines at 43, and in differential opposition for light loads, as shown in dotted lines. In all of the arrangements depending upon different conductor sections the same result may be obtained by supplying materials of different resistivities for the two coils. Specifications 17423/04 and 253,930 are referred to. Tbo Specification as open to inspection under Sect. 91 (3) (a) describes also the use in a machine with separate or any other type of excitation of a counter-compounding series coil consisting either of one winding or two windings which may be connected in series or parallel. This subject-matter does not appear in the Specification as accepted.

[Class 7 (iv)] A screening device for quick attachment to existing spark-plugs comprises a screen 6b enclosing a relatively movable insulator 10 which partially envelops the plug 9 and in which the conductor lead 8b is anchored, a spring 13 located between the insulator and the screen serving to maintain the screen in position and to ensure good connection between the lead 8b and the end of the spark-plug. In Fig. 1, the screen comprises upper and lower parts 6a, 6b permanently connected by a rolled joint, and the lower part has a flange 6d defining a hexagonal opening which slips over the hexagon 9a of the plug and is then turned through 30 degrees so that the corners of the hexagon 9a engage triangular depressions in the flange 6d. An earthing connection is made at 17. The cable 8 passes through a central bore in the insulator and the conductor is connected to a disc 12 larger than this bore so as to anchor the insulator in position. A seating washer is provided at 15. In a modification, Fig. 5, the lower part 6b of the screen slips over the screw 9c of the spark-plug and is secured when the plug is screwed home, the flange 6k serving as a gasket.

In a solid fuel furnace fed from above with a front or side air inlet grate and an opposite grate through which combustion products pass from the combustion chamber, the air inlet grate slopes downwardly and away from the fuel bed and the opposite grate slopes in the same direction but at a greater angle so that the combustion chamber narrows towards the bottom. The twin combustion chambers 2 of a boiler are fed from a single hopper I, and air is supplied from a duct 8 through grates 3 formed of water-cooled bars with fins to prevent fuel falling through the grates. Combustion products from the chambers 2 pass through water-cooled finned grates 4 to secondary combustion chambers 15. The grates 3 are inclined downwardly towards each other, and the grates 4 are inclined towards each other at a greater angle and extend below the air inlet grates 3. The narrower lower ends of the combustion chambers 2 are further constricted by ribs 7 integral with the grates 3, or by curving the bottom parts of the outlet grates 4 inwardly, as shown in dotted lines. Slag is discharged by a rotary discharger 17 to the ashpit 16.
